Patented Jan. 7, 1908.

Application filed October 12, 1906. Serial No. 388.669- Reuewed July 11. 1907. Serial No. 383320.

To all whom it may concern:

Be it known that I, ALBERT ULLMANN, a

citizen of the United States, residing at Ma con, in the county of Bibb and State of Georgia, have invented new and useful Improvements in Regulating-Valves, of which the following is a specification.

This invention relates to valves for regulating the flow of gas, steam, air, water and the like and is designed primarily for use in connection with the regulation of gas from a supply to a burner, yet the valve is adapted for any purposes wherein it is found applicable.

The invention aims to provide a regulating valve in a manner as hereinafter set forth whereby the valve can be adjusted for the regulation of gas, steam, air, water and the like at any pressure.

The invention further aims to provide a regulating valve in a manner as hereinafter set forth, which permits of a minute, as well as always obtaining a positive regulation.

The invention further aims to provide a regulating valve in a manner as hereinafter set forth, with a rotatable valvular member which not only performs its function of opening and closing the inlet and outlet of the valve housing, but also acts as a means to keep the inlet and outlet of the valve housing free from foreign matters so that when' the valve is moved to open the inlet and outlet the passage of the fluid will not be retarded.

The invention further aims to provide a regulating valve which shall be simple in its construction and arrangement, strong, durable, eflicient in its use, readily set up and comparatively inexpensive to manufacture.

With the foregoing and other objects in view the invention consists of the novel con struction and combination of parts hereinafter more specifically described and illustrated in the accompanying drawings, where in is shown the preferred embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In describing the invention in detail reference is had to the accompanyingdrawings, wherein like reference characters denote corresponding parts throughout the several views, and in which Figure l is a longitudinal sectional view of a regulating valve in accordance with this invention. Fig. 2 is a top plan View of the valve housing. Fig. 3 is an inverted view thereof. Fig. 4 is a perspective view of the valve spindle and valvular element, stop nut and packing gland. Fig. 5 is a longitudinal sectional view of a modified form of regulating valve in accordance with this invention. Figs. 6, '7 and S are, respectively, a longitudinal section, side elevation and detail of another modification. Fig. 9 is a plan showing the valve housing provided with a single outlet or inlet.

Referring to the drawings by reference characters 1 is a valve housing cylindrical in contour and bored to 'fOIll'l a chamber closed at one end, said chamber being cylindrical and of two different diameters, the smaller of which is indicated by the reference char acter 2 and the larger of which is indicated by the reference character 3, and, owing to such manner of forming the chamber a shoulder 4 is provided. The wall of the chamber is screw-threaded, with the chan nels formed by the threads of the wall of that portion of the chamber of smaller diameter cut away so as to form inlets 5 and outlets 6, the former being larger than the latter and arranged directly thereover. The housing 1 is formed with a screwthreaded nipple 7 for connecting a supply pipe thereto, screw-threaded as at 8, to enable the connecting of an outlet pipe or a gas burner thereto and is provided with a stop llange 9 for said outlet pipe or burner. The position of the inlets 5 with respect to the supply pipe is that they will be arranged approximately centrally with respect to the axis of the pipe and the same is true of the outlets 6 with respect to the burner or outlet pipe.

The reference character 10 denotes a 1'0- tatable spindle provided on its outer end with a finger piece ll and on its inner end with a screw threaded enlargement 12, which may be an integral part of the spindle 10 or suitably connected thereto and thesaid screw-threaded enlargement l2 constitutes an adjustable element for successively opening or closing the inlet ports 5 and simultaneously with the opening or closing of the inlet ports 5, successively opening or closing the outlet ports (5. In this connection it will be stated that the closure element 12 engages the screw threads of that portion 2 of the chamber of smaller diameter within the housing 1.

The inward movement of the closure element 12, which movement is had when it is desired to close the ports 5 and 6, is arrested by the inner end of the portion 2 of the chamber in the housing 1 and the outward move ment of the element 12 is arrested by a washer 13 loosely mounted upon the spindle 10. The washer 13 is of such a diameter as to be greater than the portion 2 of the chamber and is arranged within the portion 3 of the chamber. The outward movement of the washer upon the spindle is arrested by a packing 14, which surrounds the spindle 10 and the said packing is retained in position by a gland 15, which engages the screw threads of that portion 3 of larger diameter of the chamber in the housing 1. The spindle 10 extends through the gland so that it can freely rotate, but the paclting which surrounds the spindle between the washer and the gland acts as a means to prevent leakage. The movement of the washer 13- in an inward direction upon the spindle 10 is arrested by the shoulder 4. That portion of the spindle between the washer and the element 12 is of such reduced diameter as to form a passage around the same within the chamber in the housing 1 so that the gas, air, water or steam can pass around the spindle and thence be discharged through the outlets 6.

In the modification shown in Fig. 5 the housing is indicated by the reference character 16 and is bored entirely through, as at 17, to form a chamber which is of two different diameters and has the wall of that portion of larger diameter screw-threaded.

he inlets are indicated by the reference character 18 and the outlets by the reference character 19, the former being larger than the latter and are set up in the same manner as that referred to in connection with the inlets and outlets 5 and 6. The spindle is indicated by the reference character 20 and carries a screw threaded enlargement 21 which constitutes a closure element. A finger piece 22 is provided for the spindle 20 and the latter is furthermore provided with screw threads 23 which are adapted to engage with the screw threads of the wall of the portion of smaller diameter of the chamber. By this arrangement the spindle has a tight fit.

In the modification shown in Figs. 6, 7 and 8 the housing is indicated by the reference character 24 and bored to form a chamber closed at one end, said chamber being cylindrical and of two different diameters, the smaller of which is indicated by the reference character 25 and the larger of which by the reference character 26, and owing to such manner of forming the chamber a shoulder 27 is provided. The wall of the chamber is screw-threaded, with the channels formed by the threads of the wall of that portion of the chamber of smaller diameter cut away so as to form inlets 5 and outlets 6, the latter being of less length than the former. This construction is the same as that shown in Figs. 2 and 3. The housing is formed with a screw-threaded nipple 28 for the purpose of connecting a supply pipe thereto, screw-threaded, as at 29, to enable the connecting of an outlet pipe or gas burner thereto, and is further provided with a stop flange 30 for said outlet pipe or gas burner. The reference character 31 denotes a rotatable spindle having its inner edge enlarged, as at 32, and its outer end squared as at 33. The inner end 32 of the spindle 31 is provided with mutilated screw threads, as at 34,the mutilating being had by cutting away the enlarged. inner end on both sides as at 35. Surrounding that portion of smaller diameter of the spindle 31 is a packing 36, and extending in the housing engaging the screw threads of the wall of that portion of greater diameter of the chamber of the housing is a packing gland 37. The latter loosely surrounds the spindle 31 so that the same can be shifted when occasion so requires. the spindle 31 are adapted to engage in the inlets and outlets so as to close them when the spindle is given a quarter turn. This action will cause the cut-away portions on the enlarged end of the spindle to oppose the inlets and outlets, and consequently the gas can pass into, through, and out of the chamber within the housing. The spindle is shifted through the medium of the arm 38 which is mounted upon the squared end 33 of the spindle and is cut away so as to form a pair of shoulders 39 adapted to abut against a stop 40 projecting from the flange 30.

Any suitable means depending from the arm 38, so that the same can be conveniently operated, may be employed, and as shown, each end of the arm 38 carries a depending rod 41. The purpose of the modification shown in Figs. 6, 7 and 8 is to insure a quick opening and shutting of the inlet and outlet openings, as only one-quarter turn of the spindle will accomplish it. I/Vhen the regulator is out of ordinary reach, the arm 38 is provided with the rods 41, but these rods are dispensed with if the check or regulator is not out of reach.

Now, while in the employment of the regulator in connection with gas lights where a mixture of air is required, a plurality of inlets and outlets is very essential, but a single outlet can be also used for such purpose. If on the other hand the regulating valve is to be used in connection with fluids, water or steam, then in most cases a single inlet and outlet is all that is desirable, and in many cases preferable to a plurality of inlets and outlets.

In Fig. 9 the housing is shown as provided The threads on the inner portion of I with a single inlet or outlet, as the case may be, and this opening which constitutes an inlet or the outlet is indicated by the reference character 42.

By setting up the valve in a manner as shown a security against leakage is had and a positive stop for the movement of the closure element in both directions is furthermore had.

Self-cleaning regulators for gas lights employ for such purpose mechanism on the inside of the regulator body or housing to perfect such cleaning and to adjust the regulation; such mechanism, however, impedes the flow of gas, is liable to derangement, uncertain and unreliable in action. Further more it is liable to become clogged by dust, impurities in the gas, or corrosion of metals and last, but not least, adds considerable expense to the cost of the regulator. All the above defects are entirely obviated with the regulating valve constructed in accordance with this invention as it is evident that the addition of a separate mechanism for cleaning purposes or to prevent the regulator from becoming clogged is dispensed with.

In connection with the adaptation of the regulating device to a gas burner it will be stated that gas pressure in di'l'l'erent localities varies so much that it requires a regulator so constructed as to enable it to be adjusted for any pressure of gas, and unless an exact regulation is had too much gas is permitted to pass from the outlet ports and the consequence of such, is smoke and a waste of gas, whereas such objection will be obviated by the construction of regulating valve herein set forth, owing to the fact that it is adapted for use for any pressure of gas and the regulation can be very minute and furthermore positive regulation is always obtained. The

. gas after leaving the supply is divided by the large inlets, then thinned by the passage around the spindle and finally still more divided by the small outlet ports and by such an arrangement the gas will be finally divided and, therefore, will more quickly and perfectly admix with the oxygen causing thereby perfect combustion, as well as avoiding waste of gas and furthermore producing a perfectly white light, irrespective of whether the burner used is an inverted or an upright one. By employing a regulating valve in accordance with this invention there can be no possible waste of gas, so, consequently, there is no smoke, which insures the most economic use of gas, besides producing a perfectly white light. This light is practicable for all purposes of gas lights, from the open gas jet to the modern mantel light of any style and for any kind of gas.

The threads upon the elements 12 and 21 not only act as a means to open and close the inlet and outlet of the housing to regulate the amount of gas required, but also act as a means to clean or keep the inlet and outlet free from loreigi'i matter so they will not be stopped. up from any cause whatsoever. The inlet and outlet have the same pitch as the pitch of the threads 01 the closure elements, as well as corresponding in contour thereto as is evident, so that the thread of the closure element will completely close the inlet and outlet when occasion so requires in a successive manner-that is to say, the outlets will be closed successively, as well as the inlets, or opened as the case may be, so, under such circumstances a regulation can be had from the maximum to the minimum and at any intermediate point between the maximum and the minimum.

The regulation of the supply of steam, air, water and the like can be had in the same manner as the regulation of gas, and, although as betore stated, the invention is designed primarily as a gas check or regulator, yet it is adapted for any purposes or uses wherein it is found applicable.
